This was my first attempt at making a transition for the rudder cable guard. Since this piece was too short (see the left side of the picture) I figured it was expendable. I think that the best solution is going to be a combination of a piece like this one (but longer) and a door sill plate. I should be able to attach the two together.

I also spent a while on the wingtips again. This course of action has not been worth the time that it has taken. I should have just filled the old holes and gone with the basic fiberglass over aluminum mounting method.
